pullistuma

Pullistuma is an Estonian verb that describes the act of bulging, protruding, or swelling. It is used when something increases in volume or pushes outward from its usual shape, whether due to pressure, volume changes, or connective tissue and soft materials responding to forces. The term is applicable in a range of contexts, including anatomy (edema or swelling of tissues), materials and objects (a bag, a pipe, or clothing that becomes visibly thicker or stretched), and everyday observations of irregular contours.

In usage, pullistuma conveys a change of state rather than a deliberate action by a subject. The related noun pullistus denotes a bulge or swelling, while pullistumine refers to the process of bulging itself. The word tends to appear in descriptive or technical writing and can be found alongside synonyms such as paisumine (expansion) and turse (swelling) in medical or mechanical discussions. While generally neutral in tone, it can carry specific, context-dependent nuances depending on whether the bulge is considered desirable, problematic, or merely observational.

Etymology for pullistuma is not widely documented in concise dictionaries, and the form is typically treated as a native Estonian verb built through standard verbal morphology. Its usage appears more in descriptive prose and technical descriptions than in casual everyday speech, where more common terms for swelling or bulging might be preferred.
